Air traffic controllers who work at Newark Liberty National Airport are accusing the Federal Aviation Administration of not reporting "pilot deviations" in which aircraft follow the wrong departure instructions and send controllers scurrying to correct the mistakes, according to a report in the Record.

The report said the FAA declined to respond to the union's allegations and has confirmed only four pilot deviations -- two on Oct. 1 and two on Oct. 16 -- have taken place since September. "It's a nightmare," Phil Barbarello, eastern regional vice president for the National Air Traffic Controllers Association, told the newspaper. "It hasn't reduced delays. It just adds to the confusion."
